The Inn is incredibly faithfully done as it appears in canon. Its great. One small suggestion though, The common room is supposed to have a nice view of the mountains and the castle's spire in the distance. I was thinking doing something with a bay window similar to the sitting room on the Blue Water's upper floor would be a nice touch. Also, I know it probably doesn't exist in the tilesets, but making it a whitewashed building with vines growing on the exterior would be great too.
Maybe one day I will have a reason to see the inn in its entirety.
